omponents to operate profitably, face an increasingly difficult choice between owning theproducers of these items (a practice known as backward integration) and buying from independentproducers. Manufacturers who integrate may reap short-term rewards, but they often restrict theirfuture capacity for innovative product development.

Backward integration removes the need for some purchasing and marketing functions, centralizersoverhead, and permits manufacturers to eliminate duplicated efforts in research and development.Where components are commodities (ferrous metals or petroleum, for example), backwardintegration almost certainly boosts profits. Nevertheless, because product innovation meansadopting the most technologically advanced and cost-effective ways of making components,backward integration may entail a serious risk for a technologically active company-for example,a producer of sophisticated consumer electronics.

A company that decides to make rather than buy important parts can lock itself into an outdatedtechnology. Independent suppliers may be unwilling to share innovations with assemblers withwhom they are competing. Moreover, when an assembler sets out to master the technology ofproducing advanced components, the resulting demands on its resources may compromise itsability to assemble these components successfully into end products. Long-term contracts withsuppliers can achieve many of the same cost benefits as backward integration withoutcompromising a company’s ability to innovate.

However, moving away from backward integration is not a complete solution either. Developinginnovative technologies requires independent suppliers of components to invest huge sums inresearch and development. The resulting low profit margins on the sale of components threaten thelong-term financial stability of these firms. Because the ability of end-product assemblers torespond to market opportunities depends heavily on suppliers of components, assemblers are oftenforced to integrate by purchasing the suppliers of components just to keep their suppliers inbusiness.

According to the passage, all of the following are benefits associated with backward integration EXCEPT______

A．improvement in the management of overhead expenses

B．enhancement of profit margins on sales of components

C．simplification of purchasing and marketing operations

D．reliability of a source of necessary components

E．elimination of unnecessary research efforts

In recent years the basic market principles of competition and choice have expanded into new aspects of American life. Consumers now face a bewildering array of options for air travel, phone service, medical care, even postal service. Car buyers can shop on the Internet for the best price at any dealership in their area. In some parts of the country, homeowners can purchase electricity from a menu of companies. All this choice translates into unprecedented consumer power.

One of the persistent myths of capitalist culture is that business people love competition. They don’t. They spend their waking hours plotting ways to avoid it, and keep prices high. These days they use information technologies that give them intricate data on individual shoppers, and then present multiple prices to get each consumer to cough up the maximum he is willing to pay. The airlines have mastered this game, offering many levels of fares.

So how can you make the most of your new power as a consumer？ Here are rules to help you find your way.

41.______

In the New Economy, competition is so strong that fewer stores and services are immune to price pressure, so sharpen your bargaining skills. Ask retailers to match prices you’ve seen on the Internet. Ask at the checkout counter if there are any coupons or discounts you can use. Ask hotel clerks if there are better rates available. You’ll be surprised how often the answer is yes.

42.______

As competition heats up and pushes prices down, businesses scramble to boost their profits by heaping on extras: rust proofing your car, service contracts on your appliance, prepaid gasoline for your rental car. These stunts are devised to make you pay more at the last minute and probably aren’t a good deal.

43.______

The information highway is a two-way street. As a consumer, you can get more data. But while you are roaming the Web, businesses are studying your habits and vulnerabilities.

Have a weakness for chocolates？ Don’t be surprised if Amazon. Com offers to sell you a box while you’re browsing for books. They’re using a wrinkle on the last-minute marketing pitch perfected by McDonald’s: “Would you like fries with that？” The ploy works remarkably well.

44.______

Versioning is a tactic used by businesses to separate status-conscious consumers from the bargain-hungry ones — since the former mean bigger profit margins. “Deluxe” and “platinum” are code words used to entice status seekers to open their wallets.

Add a third price level and the purses of even bargain-hungry shoppers can be pried open. Research shows that many consumers who might pick the lower-priced option when given just two choices will choose the medium-priced alternative if given three. “Consumers try to avoid extreme options,” write Carl Shapiro and Hal R. Varian in their book Information Rules.

Consumers in .the New Economy face more demands on their time and attention than ever before, so they’re inclined to make the most familiar choice. Consider this: it had been a decade and a half since the breakup of AT＆T, yet it is still by far the largest long-distance provider — even while other phone companies offer $ 50 worth of free service for switching. More than ever, it pays to change services and brands.

If you don’t want the hassles of switching remember that businesses are eager to hang on to consumers. The next time you get a tempting offer from a credit-card issuer or a phone company, call your current provider and ask them to match t
